The Control Techniques UNI3403 is a universal inverter from the Unidrive Classic range. Its model designation identifies frame size 3 in the 400-V class. According to the manufacturer manual, the unit is designed for a three-phase 380 to 480 V AC mains supply with a permissible tolerance of ±10 percent and a frequency of 48 to 62 Hz. The rated power is 22 kW or 30 hp. Control Techniques specifies switching-frequency-dependent continuous output currents at 40 °C: 46 A at 3 or 4.5 kHz, 40 A at 6 kHz, 32 A at 9 kHz and 26.6 A at 12 kHz. This allows the current class to be selected for the intended switching frequency and thermal design. On the input side, the documented figures are 40 A typical input current and 53 A maximum continuous input current. The UNI3403 supports the universal motor-control functions provided by Unidrive Classic for open-loop, closed-loop and servo applications. Communication and feedback functions are added through suitable option modules; their installed configuration should be checked on the existing unit. The inverter uses forced ventilation. Its degree of protection depends on the mounting arrangement: IP00 without cable-entry plates, IP10 with the plates fitted, and IP40 or NEMA 1 with plates and suitable cable glands. The RFI or EMC filter is external and optional rather than integrated into the base unit. Dimensions are 368 × 375 × 260 mm and the weight is 22 kg. Before replacement, compare the complete model number, voltage class, switching frequency, current class, mechanical installation dimensions, cooling, installed option modules and filter arrangement. This clearly distinguishes the UNI3403 from similarly named Unidrive models. Shipping method and cost are confirmed according to the destination and consignment details.
